The most likely answer is Evans Sabwami , who is identified in public reporting as Gloria Muliro’s husband and in the same context where Lady Bee is mentioned.

Context

The phrase “Lady Bee” is ambiguous because it refers to more than one person in public sources, so the exact husband depends on which Lady Bee you mean.

Other possible match

If you meant Bernice Nduku Mugo , known as Lady Bee in Kenyan media, public reporting does not clearly name her husband in the source I found.

Note

If you meant a different Lady Bee, the husband’s name could be different, since the name is used by multiple public figures.
